About Base85 Encoder
Base85 (also called Ascii85) is a notation for encoding arbitrary byte data. It is usually more efficient that Base64. This operation encodes data in an ASCII string (with an alphabet of your choosing, presets included). e.g. hello world becomes BOu!rD]j7BEbo7 Base85 is commonly used in Adobe's PostScript and PDF file formats. Options AlphabetStandard - The standard alphabet, referred to as Ascii85 Z85 (ZeroMQ) - A string-safe variant of Base85, which avoids quote marks and backslash characters IPv6 - A variant of Base85 suitable for encoding IPv6 addresses (RFC 1924) Include delimiter Adds a '' delimiter to the start and end of the data. This is standard for Adobe's implementation of Base85.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.
Format reference: To Base85 background and specification

Input
Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.

Before interpreting the result
Choose a decoder for an encoded payload, an encoder for transport, or a converter for structured data. Hex and Base64 represent bytes; converting formats does not encrypt or authenticate them.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
